[0023] Please see Figure 1-4 One embodiment of this utility model is a low-altitude logistics monitoring device based on a temperature and humidity sensor, comprising a multi-rotor drone 3.

[0024] The protective device 6 includes a positioning rod 8, a pressing crossbar 9, a temperature and humidity sensor 10, bolts 11, a plastic round plate 12, a support frame 13, and a support base plate 14.

The support base plate 14 is fixedly installed at the four corners inside the support frame 13. The plastic round plate 12 is fixedly installed at the four corners outside the support frame 13. The bolts 11 are symmetrically rotated and installed at the top of the support frame 13. The pressing crossbar 9 is threaded onto the outer ring of the bolts 11. A plastic sheet is fixedly installed on the outer ring of the plastic round plate 12 to prevent rigid collision between the plastic round plate 12 and the support cavity 16.

[0025] The connecting device 7 includes a buffer spring 15 and a support cavity 16. The buffer spring 15 is symmetrically fixedly installed at the top inside the support cavity 16. The connecting device 7 includes a buffer spring 15, a support cavity 16, a plastic strip 20, a U-shaped positioning bracket 21, and an electric push rod 22. The buffer spring 15 is symmetrically fixedly installed at the top inside the support cavity 16, the electric push rod 22 is symmetrically fixedly installed at the bottom inside the support cavity 16, the U-shaped positioning bracket 21 is fixedly installed on the end of the electric push rod 22 near the buffer spring 15, and the plastic strip 20 is fixedly installed on the U-shaped positioning bracket 21. The positioning frame 21 is located on the side opposite to the electric push rod 22. The collection device 5 includes an insulated cargo box 17, a drawer 18, and a guide rail 19. The guide rail 19 is symmetrically fixed on both sides of the interior of the insulated cargo box 17. The drawer 18 is slidably inserted into the guide rail 19. The collection device 5 includes an insulated cargo box 17, a drawer 18, and a guide rail 19. The guide rail 19 is symmetrically fixed on both sides of the interior of the insulated cargo box 17. The drawer 18 is slidably inserted into the guide rail 19. By setting the buffer spring 15, the vibration of the insulated cargo box 17 transmitted to the temperature and humidity sensor 10 can be reduced.

[0026] The support frame 13 is fixedly installed on the end of the buffer spring 15 away from the support cavity 16. The support cavity 16 is fixedly installed at the bottom center of the insulated cargo box 17. The insulated cargo box 17 is fixedly installed at the bottom center of the multi-rotor UAV 3 and can support the placement of goods.

[0027] The positioning rod 8 is slidably inserted into the top of the support base plate 14. By sliding the positioning rod 8 into the top of the support base plate 14, the temperature and humidity sensor 10 can be placed.

[0028] The drawer 18 has keyed buttons fixedly installed on both sides, and the guide rail 19 has a slot near the inside of the drawer 18. The temperature and humidity sensor 10 is wirelessly connected to the ground signal receiver 23. The multi-rotor UAV 3 is equipped with a temperature and humidity alarm module 24. The temperature and humidity sensor 10 collects the temperature and humidity inside the insulated cargo compartment 17 and transmits the data to the ground signal receiver 23, so that the signal receiver 23 can display the temperature and humidity inside the insulated cargo compartment 17 in real time. The signal receiver 23 can be a mobile phone, remote control, or computer screen. At the same time, the temperature and humidity sensor 10 collects the temperature and humidity inside the insulated cargo compartment 17 and transmits the data to the flight control system in the multi-rotor UAV 3. The flight control system is equipped with the temperature and humidity alarm module 24. At the same time, there is a wireless signal connection between the ground multi-rotor UAV remote control device and the temperature and humidity alarm module 24, so that the ground multi-rotor UAV remote control device can display the temperature and humidity inside the insulated cargo compartment 17 and alarm information in real time.

[0029] Working principle: In use, goods are placed on drawer 18, and then drawer 18 is pushed into the insulated cargo compartment 17, allowing for layered placement of goods. Simultaneously, the drawer 18 slides along the guide rail 19 via latches on both sides, supporting its linear movement. The insulated cargo compartment 17 prevents goods from spoiling or melting during transport. After the goods are placed, the cabinet door of the insulated cargo compartment 17 can be closed to prevent goods from falling during transport. Then, the multi-rotor drone 3 can be activated and ascend to a designated altitude to transport the goods. During transport, sensors within the insulated cargo compartment 17 communicate with the interior of the compartment. This allows the temperature and humidity sensor 10 to record and sense the temperature inside the insulated cargo compartment 17 in real time. Simultaneously, the temperature and humidity sensor 10 has a wireless signal connection to an external display terminal, enabling it to send signals to the display terminal for users to monitor the temperature inside the insulated cargo compartment 17. When the support legs 2 need to land, the multi-rotor drone 3 can make contact with the ground. The buffer spring 15 absorbs the vibration potential energy of the multi-rotor drone 3, preventing it from being transmitted to the temperature and humidity sensor 10. Furthermore, the plastic circular plate 12 prevents the temperature and humidity sensor 10 from colliding with the inner wall of the support cavity 16 during shaking, thus preventing damage to the sensor 10 from vibrations and completing the cargo transportation process. In operation, when the temperature and humidity sensor 10 needs to be installed, it can be placed inside the support frame 13 until the positioning rod 8 is inserted into the support base plate 14. Simultaneously, the pressing crossbar 9 can be rotated until it is perpendicularly aligned with the edge of the temperature and humidity sensor 10. Then, the bolt 11 is tightened to move the pressing crossbar 9 downwards, thus pressing and confining the temperature and humidity sensor 10 onto the support base plate 14. During use, the combination of the buffer spring 15 and the plastic circular plate 12 prevents vibrations from the multi-rotor drone 3 during landing from affecting the temperature and humidity sensor 10, extending its service life. Furthermore, the sensing head in the temperature and humidity sensor 10... The insulated cargo compartment 17 is internally interconnected, allowing the temperature inside the compartment to be transmitted in real time to the temperature and humidity sensor 10 for display. When the multi-rotor drone 3 is in flight mode, the electric push rod 22 can be activated, causing the U-shaped positioning frame 21 to move towards the center of the support cavity 16 until it contacts the outer surface of the support frame 13. This fixes and secures the support frame 13, preventing the temperature and humidity sensor 10 from shaking during flight. Simultaneously, the plastic strip 20 prevents the U-shaped positioning frame 21 from damaging the surface of the support frame 13, thus completing the positioning of the support frame 13. When the multi-rotor drone 3 needs to land, the electric push rod 22 can be activated again.The U-shaped positioning frame 21 is moved away from the support frame 13, allowing it to disengage. At this point, a gap exists between the support frame 13 and the support cavity 16, and the buffer spring 15 is connected to the outer surface of the support frame 13. This allows the support frame 13 to sway up and down inside the support cavity 16 during landing, preventing the temperature and humidity sensor 10 from colliding with the support cavity 16. In use, the multi-rotor drone 3 has a built-in wireless communication module that is wirelessly connected to the temperature and humidity sensor 10 and the temperature and humidity alarm module 24, enabling the wireless communication module to transmit information about the temperature and humidity sensor 10's operation to the outside world.
